Title: Scorotron system electrifier
Inventor: MATSUSHITA KOJI
IPC: G03G15/02
Filed: 1994-08-23
Abstract: PURPOSE: To clean the surface of a grid on a side opposed to a body to be discharged without possibility of damaging the body to be discharged, to maintain the positional accuracy of an electrifier and to perform stable electrification by allowing a cleaning member to travel along the surface of the grid opposed to the body to be discharged and cleaning the grid. CONSTITUTION: By starting the operation of a motor 616, a cleaning member supporting body 61 is moved from a standby position to a cleaning area P2. A cleaning member supporting lever 62 is turned by a tension spring 624 coupled with the lever 62, and the cleaning member 7 passes a position R2 to abut on the surface of the grid 2 opposed to the photoreceptor drum. At such a time, the cleaning member 7 press-contacts with the grid 2 while pressing the grid 2 in a direction going away from the photoreceptor PC from a regular position when cleaning is not performed. Thus, the surface to be cleaned of the grid 2 is rubbed and cleaned by the cleaning member 7. Since the electrifier A itself is still put at a specified position whether it is non-cleaning time or cleaning time, its positional accuracy is maintained.

Title: Elastic coupling
Inventor: OMOTO YUICHI
IPC: F16D3/62
Filed: 1986-08-25
Abstract: PURPOSE:To enable the oscillation of an elastic coupling to be effectively prevented by changing the length of the first elastic member from that of the second elastic member, thereby changing the spring constant in the normal rotational direction from the spring constant in the reverse rotational direction. CONSTITUTION:When a drive shaft is normally rotated in the direction of an arrow B, the first clamp 1 is also rotated integrally with the drive shaft in the same direction. When the drive shaft is normally rotated, tensile stress is effected on the second elastic member 4; especially on the reinforcing cord member 40, and the compressive force is effected on the first elastic member 3; specially on the reinforcing cord member 30. The length of the second elastic member 4; especially the length of the reinforcing cord member 40 of the second elastic member 4 is set longer than that of the first elastic member 3. Therefore, the oscillation is effectively prevented because the spring constant in the driving direction which is the normal rotational direction can be raised, and the spring constant in the anti-driving direction which is the reverse rotational direction can be reduced.

Title: Signal processing method and apparatus
Inventor: KENESU DEIRU FURENDO
IPC: G06M1/10
Filed: 1985-09-09
Abstract: A linear array of light emitting diodes (CR1-CR7) direct a diffuse beam of radiation across the path of seeds dropping down a seed chute and onto two detectors (46,48) connected in parallel, so that every seed produces a substantially equal area pulse in the output signal from the photo detectors. The signal is amplified (50) and applied to an analog to digital converter (52) producing digital samples at a high rate for processing by a microprocessor (54). The sensor value is subtracted from an offset value corresponding to the sensor signal when no seed is present and the difference signal is repeatedly added to an area signal. The offset value is adjusted from time to time to prevent the difference signal staying persistently negative or persistently positive. Whenever the area signal reaches a threshold value the passage of a seed is indicated and the area signal is decremented by an estimated area value corresponding to one seed. This estimated area value is adjusted from time to time so as to avoid long term drift in the area value, thereby maintaining the estimated area value accurately representative.

Abstract: PURPOSE:To calculate scratch hardness while measuring displacement and a load at the same time by providing an electronic balance, a piezoelectric actuator, and a parallel movement driver, etc., and making a scratch stably while placing the load on an indentor. CONSTITUTION:A sample 1 is placed on the sample pan 3 of the electronic balance 2. A diamond stylus 4 whose tip is of 0.1mum in radius is manufactured by electrolytic polishing and put closer to the sample surface by the piezoelectric actuator 5. Then the stylus 4 is stopped from being fed where the stylus 4 contacts the sample surface and its load is detected, and then parallel movement driving 6 is performed through an amplifier 11 to move the stylus 4 in parallel to the sample surface; and the actuator 5 is driven at the same time to place the load continuously. Further, the depth of a scratch is monitored by a reflection type displacement measuring instrument 8 by reflecting light passed through an optical fiber 9 through the same measuring instrument 8 to a mirror 7. At this time, a personal computer 10 brings the actuator 5 under servocontrol according to the signal of the measuring instrument 8 for uniform loading, thereby preventing displacement from varying owing to the jumping of the indentor.
